STEBER, a citizen of the United States, residing at have invented certain new and declare the follow ing to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which .it appertains to make'and use the same.

This Ainvention relates to cloth guiding machines land has for an object to provide an electrically actuated cloth guiding apparatus especially adapted for use in conjunction with the cloth slitting machine disclosed in Patent No. 1,025,981, reissued Feb. 11th, 1913, No. 13,528.

A further object of the invention is to provide electrically actuated mechanism for moving a beam longitudinally from which is unrolled and with. means actuatedl by the position of the cloth web for energizing the motor of the. controlling mechanism.

A further object of the invention is .to

' provide in conjunction with means for moving a web of cloth a star wheel proportioned to' follow between two given warp threads and tovmove an arm carrying an electrical contact whereby a motor controlling the position of the beam is rotated in either direction necessary to move such beam.

A further object of the invention is to provide a longitudinally slidable beam with means for moving such beam longitudinally, and an electric motor adapted tol actuate the controlling means. v

\A further object of the invention is.l to provide spaced contacts with an arm movable between the contacts, in circuit with a motor and improved wiring"' whereby the f movement of the `arm into engagement with In the drawings :Figure 1 is a perspective.

The improved cloth guidingpmechanism which forms the subject matter of this application is adapted for a multitude of 'uses but is shown in connection with a cloth slitting machine similar tothat disclosed in the aforesaid patent and pending reissue application, auch machine being shown as a whole at 10. The beam 11 uponwhich the cloth fabric 12 is Wound is mounted upon a shaft 13 rotatable and longitudinally slidable in bearings 14.

At lone end of the frame a lever 15 is fulcrumed provided with a pintle 16`seen especially at Fi 2 engaging in a furrow in a disk 17 carriedv upon the shaft 13 so that as the lever 15 is moved upon its pivot it moves therewith the shaft 13 and beam 11.-

To move the lever 15 such leveris provided with'a nut 18 with ascrew 19 inserted therethrough which also` finds a bearing at y 20 in the frame and carries a gear wheel 21. Journaled adjacent such gear wheel 21 is a shaft 22 carrying a worm 23 and rotated through the medium of gears 24 from a motor 25. 1t will be apparent therefore, that the motor 25 is rotated the beam 11 will he moved longitudinally the direction of movement depending upon the direction 0f rotation of the motor 25.

To control the erotation of -themotor 25 a cleat 26 is mounted upon the frame and at some point intermediate its ends provided with eight contacts s aced in groups of four upon each side o a neutral indicated at. 27. The eight contacts are grouped 28, 29, 30 and 31 upon one side of the neutral 27 and 32, 33, 34 and 35 upon the opposite side of the neutral. Mounted also adjacent the beam. 11 is a vertical rod 36 vadapted to swing upon its axis and carrying an arm 37 pivcted to a collar 38 in such manner as to permit vertical movement upon its pivot but to prevent angular movement in its plane of movement Without moving the shaft B6.

such threads a distance upon each side suflif throughout the length of the cloth and if i and 46 upon :one side v4`v f-ifin1`llu battery :72 through the wire 33 to 5 4in1 mutant 1)-3, through the connected fingers Fig. 3 and the extremity the stai-wheel 39 the contact brushes will be the contact 29, returning through the wire the Wire GOto the contact 35, through the .S51-.bu the field :37 reversing thc field, through The arm 37 is provided with a star wheel 39 similar to the star wheel in said patent. sho-Wn at 67 and in the reissue application as 40. The star wheel 39 is provided with teeth 40 of such width and contiguity that when one of the teeth is inserted -between the warp threads of a'w'eb of cloth it spreads cient to insure the next tooth-being inserted into such space and between the same threads so that the star Wheel 39 will at all timesfollow vbetween the same warp threads the position of such 'Warp threads to4 the cleat 26 Varies they Will move the star vWheel 39, the arm 37 and rod 36. Carried also by the rod 36 is a collar 41 to which is pivoted an arm 42 moved therewith the same as the armv 37 and carrying contact brusheslnormally restingupon the neutral 27. The eentaet brushes 'comprise four spring members eachA bifurcated to form fingers 43,144, 45 of the arm and'47, 48. 49 and 50 upon the opposite side of the arri 42. The spring fingers of the contact brushes are` bent as shown particularly at of the arm carry-' ing such brushes 1s insulated from the remainder of the arm as indica-ted at 51. It will be apparent, therefore, that as the arm 42 is moved Ain response to the movement of mpved lgrom the neutral 27 in leither direction andthe groups of contact fingersfwill engage ille groups of contacts upon either side of theneutral 27. Referring now more particularly to Fig. 6, it'will be apparent that when the arm and contact fingers are moved to the right the fingers 43, 44, 45 and 46 will respectively engage thecontacts 28, 29, 30 and 3l and the cu'rren will flow from1 the battery 52, through the wire 53 as .indicated by the featheredmrrows -to the contact 33, through the wire 54 to the contact 28, and through the connected fingers 43 and 44 to 55, contact 34, wire 56 to the field 57 energizing such field, then through the wire 58 to the Contact 32, thro-ugh the wire 59 to the contact. 30` then through the connected fingers 45 and 46 to the contact 3.1,then through Wire 61 to the motor 25 and through the wire 62 back to the battery all as indicated by the feathered. arrows and to rotate the motor in `the direction indicated by -the `Web of cloth, of

feathered arrows thereon. ThenA the arm 4.2 is moved in the opposite direction the fingers 47 to V50 inclusive will engage the contacts 32 'to inclusive and the current will flow as indicated by the single arrow -i and 4S tothe Contact 32, through the wire the wire 56 to the contact 34, through the connected lingers 49 and 35, through the Wire 61 to the motor 25, which by reason of the reversal of the field will rotate in the op through the wire 62 to the battery. It will thus be apparent that s the arm 42 oscillates under the control pf the star wheel 39 the beam l1 will be longitudinally moved `to mov the web of cloth in the direction opposite to that of the movement of the star wheel whereby the irregularity of the web of cloth will be overcome by the movementof the beam.

Thebrushes are provided with slots 63 engaged by'screws 64 by which the brushes may be adjusted relative tov the insulated extremity 5l to permit a greater or less throw of the'arm 42 so that the beam 11 will be moved to guide the web of'cloth to compensate for greater or less inequalities or unevenness of livind. -v I claim: v 1. `The combinationo with a cloth slitting machine embodying means for` moving a a longitudinally movable beam carrying the Web of cloth, movable means to follow between two Ik:predetermined warp threads of the web of cloth, beam longitudinally site to the movement means.

2. The combination with a cloth 4slitting machine, of a beam carrying a web of cloth,
